Winged Spatha?
Your charr’s butt is not deserving of the full model, unlike that human and her cute butt. No seriously. The weapon models differ a little bit for each race, with the main difference being scaling. It looks like ANet just missed a spot. Seeing as you posted this in the bug forum, it has probably been put on a todo list somewhere by an ANet employee. Like the wait for the tummy seam on the winged set to be fixed (thanks ANet), it will just take waiting on your part. Sorry there’s not much else you can do for no.
Hi, can I know where did you find it? There isn’t any recipe or vendor in the wiki.
This is not a bug, the wiki preview is wrong. The actual preview resembles the actual ingame screenshot.
I have the actual weapon and the preview looks identical to ingame model (see: http://dulfy.net/2012/12/06/gw2-sword-skins-gallery/#62)
I think what you have is the Light Sword of Air you get from the story line. http://wiki.guildwars2.com/wiki/File:Light_Sword_of_Air.jpg
